'I still love biology, but more and more it is geology ... that gets me excited.' Designing her classes with hands-on activities similar to those shared in the AAPG-AAPG Foundation-sponsored 'Rocks in Your Head' conference, Peggy Lubchenco teachers her junior high students about the surrounding area's geology.

Oil and gas discoveries of the 90s were significant in location but less so in size. How does this impact the future? 'To meet the current annual demand ... and the demand ... in 2010, new production must originate from a variety of sources...,' says Robert Esser, director of Global Oil and Gas Resources with Cambridge Energy Research Associates.

Real-time well analysis that takes place during actual drilling helps manage deviations that are too small to detect with seismic data, but could interefere with drilling. 1998 Pacific Section H. Victor Church awarded for a poster session on a project in Ventura, California, shares the 'Advantages of Real Time LWD Dipmeter Data.'

Oil and gas seeps have provided resources that have been recorded everywhere. Their importance led to a symposium, field trip and workshop on this topic at this year's AAPG Pacific Section meeting. Drawing earth scientists from across the United States and around the world, it served as a forum for the development of a plan for the global analysis of fluid seeps.

Rare is the financier who can look at a 2-D map and visualize the pertinent data in three dimensions. But when a 3-D model is available, the folks who deal with capital can better understand complex geological concepts by actually seeing fault closure, stratigraphic traps and such, thereby leaving less to the imagination.

A focus on mid-career training for geologists again topped the actions taken by the 1998-99 AAPG Executive Committee, as funding was approved for the first international training center.

Earthquakes in the center of the country. It's a great story, but whether true or not, a big question remains: Could it happen again today?

Jane Woodward was impacted by the contraction in the oil industry in the mid-1980s, but for her the impact was actually positive.

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

VG Abstract

Hydraulic fracturing has been around for decades. This talk describes some of the first applications of the technology, how it developed over time, and our current understanding of its impacts with some discussion of both water and earthquake hazards.
